3. Setup and Initial Use
The RCYAGO Soil pH and Moisture Meter requires no assembly or batteries. It is ready for use directly out of the packaging.
3.1 First-Time Use
- Gently clean the metal probe with a soft cloth before first use.
- Ensure the soil is moist. If the soil is dry, water it thoroughly and wait 20-30 minutes before testing.

4. Operating Instructions
4.1 Measuring Soil pH
- Insert the metal probe into the soil clockwise, ensuring it reaches a depth of at least 10cm (approximately 4 inches) for accurate readings. The probe should be in full contact with the soil and compacted.
- Wait for the pointer on the dial to stabilize (typically 5-10 minutes).
- Read the pH value directly from the dial. The pH scale is usually indicated with a range of 3-8.
- For multi-point measurement, repeat the process in different areas and average the values for a comprehensive understanding of your soil's pH.

4.2 Measuring Soil Moisture
- Insert the metal probe into the soil as described for pH measurement.
- Press and hold the white button located on the side of the meter. The pointer will automatically jump to the humidity reading.
- Wait for the pointer to stabilize before reading the moisture level.
- Release the button to return to pH measurement mode.

5. Maintenance
- Clean After Use: Always clean the electrode head thoroughly after each use to remove any soil particles.
- Keep Dry: Ensure the probe is completely dry before storing the meter.
- Storage: Store the meter in a dry place, away from direct sunlight and extreme temperatures.
- Avoid Liquids: This product is designed exclusively for soil testing. Do not use it for testing any liquids.
6. Troubleshooting
- Inaccurate Readings: Ensure the soil is adequately moist. Dry soil can lead to inaccurate or no readings. Water the soil and wait 20-30 minutes before retesting.
- Pointer Not Stabilizing: Make sure the probe is fully inserted into the soil (at least 10cm deep) and compacted. Loose contact with soil can affect stability.
- Difficulty Switching Modes: When measuring humidity, press and hold the button until the pointer stabilizes. Releasing the button will revert to pH mode.
- Probe Damage: Do not use excessive force when inserting the electrode into hard or rocky soil, as this can damage the probe.
- No Reading in Liquids: This meter is specifically designed for soil. It will not provide accurate readings in water or other liquids.
